Approved feed fluids

+ Fresh water with very low particle content (size <0.5mm), free of chemicals or sand residues, such as rainwater, runoff or pond water.

The operating principle of the installation is based on create a movement of fluid, suck it and creating pressure due to centrifugal force generated by the movement of the impeller of the pump. When you turn on the pump, the liquid in the turbine is pushed from the center of the wheel to the periphery by centrifugal force, which leads to the creation of a flow, and to the periphery, increased pressure, the result is that the fluid in the pump begins to flow through the pump outlet

by centrifugal force, which leads to the creation of a flow, and to the periphery, increased pressure, the result is that the fluid in the pump begins to flow through the pump outlet.

FR ES EN The installation is controlled by a pressure switch. When the pump is turned on, the water enters the tank until the set upper pressure is reached on the pressure switch, the pump is stopped. The liquid is discharged without starting the pump until the liquid pressure in the tank reaches the lower mark ofthe pressure set on the pressure switch. Then the cycle repeats itself.

- À preliminary fiker, in order to avoid unnecessary damage to the pump as a result of stones and solid

- À suction-hose set with suction hose and an intake valve with a strainer (in order to prevent long

- If you cannot obtain a suction-hose set, please purchase :

- an 25 mm (1") intake hose

- an intake valve with a strainer

- 2 hose clamps 2 standard adapters (one for the suction hose, one for the discharge line) and assemble the suction-hose set yourself using a standard adapter and a clamp.

Attach the filter to the wall. Make sure that the vibrations of the pump do not damage this installation (flexible connection is strongly recommended)

beginning of this manual including all text under subheading

û WARNING ! Read the « SAFETY INSTRUCTION » section at the therein before using this product.

Pay particular attention using the machine for the first time : focus and dedicate all your attention to this first use.

Connecting the suction hose æillustration (2.5)

+ Screw the standard connectors onto the suction connector.

+ Assemble the suction hose using a standard connector and clamp. Make sure the assembly is tight enough as a leaking suction hose will draw in air instead of water.

+ Ifthe water is not so clear, add a filter between the suction connector and suction hose.

Risk of damage tothe purps

If without filter: unwanted particles (sand, stones, etc.) will cause damages to the pump. Any damage caused in this way will not be covered under our warranty

Risk of damage to the pump! The hose adapters on the suction and discharge connectors must only be tightened by hand to avoid damage to

connectors. If water leaking at the connector, seal the joint with PTFE tape (not included).

+ Position the suction hose so that it rises from the water withdrawal point to the pump. Avoid positioning the suction hose higher than the pump, as this would delay the escape of air bubbles and impede the priming process.

- The end ofthe intake valve should be low enough in the water to ensure that if the water level falls, the pump will not run dry.

- A leaking suction hose will draw in air instead ofwater. Please make sure the clampis properlytightened. - For suction heights exceeding 3 m we recommend securing the suction-hose (e.g. by fastening it to a wooden post). This relieves the pump of the weight ofthe suction hose.

- Install the intake and discharge lines in such a way that they do not place the pump under any mechanical strain.

Priming the pump æ illustration to

First, unscrew the filling plug to remove air from the pump during filling.

Fill the pump with clear water via discharge connector. Filling must be done slowly so that the air contained in the pump is completely expelled. Fill to overflow and put back the filling plug. As this is not an auto-priming pump, the suction pipe will also need to be filled. To save time when filling, you can detach the suction pipe set and fill it directly (by submerging the suction pipe in water, for example) before connecting the pump.

Depending on the suction height and the amount of air in the suction hose, priming can take anywhere between 1 minute to 5 minutes. fit takes longer than this, the pump should be refilled with water.

— Illustration (5.3) Always remove the plug from the socket before refiling !

4.4 OPERATION Start the pump æ illustration (3.1) to (3.3)

— Illustration (6.3) and

Check that the filter and the valve are clean. If not, clean them as shown in the illustration. 8.2 MAINTAIN

+ Have your product serviced by a qualified repair person using_ only identical replacement parts. This will ensure that the safety of the product is maintained.

+ Have the product checked by a qualified professional and

repaired, if necessary, before you use it again.

Regular checks + Illustration (5-1)

Check monthly the tank pressure using a manometer (not provided).

Inside the tank, there is a flexible membrane and an air compartment whose maximum pressure must be around 1.8 bar. Water under pressure causes the membrane to expand in such a manner that pressure in the air compartment increases until it reaches the stopping pressure. If the air pressure is too low raise it by inflating the tank. In order to do this, unscrew the cover of the tank valve, then inflate the tank up to 1.8 bar using a manual pump fitted with a manometer.

-Ifthe pressure is lower than 1.2 bar: Inflate the tank to the right pressure. - Ifthe pressure is higher than 1.8 bar: Deflate the tank down to the right pressure. When inflating the tank, never exceed the pressure of 1.8 bar.

Before checking the tank pressure, make sure that all the discharge circuit valves are open in order to empty all the water that is Under pressure, and thus obtain an exact measurement ofthe air pressure in the tank.

Changing the membrane + Illustration (5.2)

After performing the checks indicated in the Troubleshooting section, if the membrane needs to be changed, proceed as follows: (it is strongly recommended to get some help from a specialist.)

+ Unscrew the cover of the tank valve, then push the valve to release all air completely.

+ Unscrew the hose from the tank flange.

+ Using a key, unscrew the 6 bolts of the tank flange.

+ Remove the flange. Take out the defective membrane, then replace it with a new membrane.

+ Assemble back the flange and the hose, proceeding in the opposite order to that of disassembly.

+ Inflate the tank through its valve until it reaches the pressure level of 1.8 bar.

+ Screw the cover back on the tank valve.
